Title: Densitometer
Inventor: CELIO TINO
IPC: G01J1/16
Filed: 1970-03-02
Abstract: 1298517 Densitometer CIBA-GEIGY A G 2 March 1970 [28 Feb 1969] 9949/70 Heading G1A A two path arrangement including a logarithmic element 7 Fig.1, for determining the optical density of a sample 3 from the light reflected from the sample 3 and a reference 4, includes a servo-amplifier 9 to maintain signals produced in a photo-diode 6 at a substantially mean value corresponding to the mean of the intensities in the two paths so that the working point of the logarithmic element and of the other circuitry is maintained substantially constant. The servoamplifier may control the brightness of source 1 or the amplification of photo detector 6. A polarity reverser 10 produces a signal dependent upon the difference in intensity in the two paths which is indicated in a meter 11 and provision is made at 19 for the introduction of an adjustable reference value by a gate 18 opening only during the reference value pulses. The optical path includes polarization filters 14,15 a chopper 2, and a filter wheel 5 for colour investigation which may be controlled by a unit 20 to drive the filters to a position of maximum detector signal. In a further arrangement the voltage value differences formed by the polarity reverser are passed to a store (23) Fig.3 (not shown) by means of a distributor (25). The drive motor for the filter disc 5 is not controlled by the control voltage detector unit 20 as above but runs in synchronism with the distributor. The control voltage detector unit 20 detects which filter produces the maximum control voltage and on completion of a rotation of the filter wheel causes a gate circuit (24) to pass to an indicator (11) the pair of reference and measurement voltages which cause the maximum control voltage to be produced. Further similar embodiments are described with multiple indicators (one for each location in the store) and with multiple reference bodies.

Title: Process for coating surface of aluminium and aluminium alloys
Inventor: MITANI MINORU
IPC: C25D11/06
Filed: 1990-05-09
Abstract: A method of treating the surface of aluminum or its alloy to give a desired color thereto and, in addition, improve the abrasion and corrosion resistances thereof. An anodic coating formed by the Almite process was disadvantageous in that it was porous, had low abrasion and corrosion resistance and was unsatisfactory in color fastness. The method of the invention is characterized by forming an anodic coating on the surface of aluminum or its alloy by an ordinary process, dipping the product of anodization in a solution of a sulfate or nitrate of a desired metal, and applying an AC voltage of 10 to 30 V thereto to thereby infiltrate the metal into the anodic coating by electrolysis. As a result, the metal is embedded in the pores of the porous anodic coating to thereby improve the abrasion and corrosion resistances, and the embedded metal serves to attain desired coloration.

Filed: 1978-01-11
Abstract: PURPOSE:To let one switch serve both as a snooze switch and a stopping switch by detecting the operation times and operation time of the switch and controlling the snooze and stopping of the alarm. CONSTITUTION:The set output of an FF 38 corresponding to the operation of a switch 18 is applied to a first detection circuit 22 when an alarm is sounding and an inhibit gate 26 is held released. As a result, one operation of the switch 18 is detected and the snooze state where the alarm sound is stopped for a specified time by a snooze control circuit 14 is set by the set output of the circuit 22. On the other hand, the second detection circuit 20 which is constituted by FFs 64 thru 66, etc. resets the FF 30 of an alarm coincidence memory circuit 12 to put the alarm in the stop state by way of an OR gate 72 as the output of its FF 66 inverts only when the switch 18 is pushed and operated long more than a fixed time. Hence, one switch may be served both as a snooze switch and an alarm switch.
